Use the linear formula y=m x + b
Using the normal approximation to the binomial, it is found that there is a 0.0107 = 1.07% probability that more than 30 are single.
<h3>Normal Probability Distribution</h3>
The z-score of a measure X of a normally distributed variable with mean
and standard deviation
is given by:

- The z-score measures how many standard deviations the measure is above or below the mean.
- Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.
- The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with
.
In this problem, the proportion and the sample size are, respectively, p = 0.22 and n = 200, hence:


The probability that more than 30 are single, using continuity correction, is P(X > 30.5), which is <u>1 subtracted by the p-value of Z when X = 30.5</u>, hence:


Z = -2.3
Z = -2.3 has a p-value of 0.0107.
0.0107 = 1.07% probability that more than 30 are single.

Take shelter in a basement or any where underground. It is the best way so you don;t get effected if you were in a building abouve ground because windows can break and dangerous items may fly in from the wind. Hope this helps
Answer:
B

Here, we are asked what molecule carries the message that is translated into a protein.
- The molecule which carries the message that is translated into a protein is the messenger RNA (mRNA)
RNA - Ribo-nucleic acid.
The type of RNA which are characterized by the containment of the information for translation into a protein are messenger RNA (mRNA) because they convey the information, or message, from the DNA out of the nucleus into the cytoplasm where Translation occurs. Translation, which is the final step in conversion from a gene to a protein, takes place in the cytoplasm.
P.S: Protein synthesis occurs in the cytoplasm.
